T0 all whbm it may concern:

Be it known that I, LOUIS GODDU, of Wnchester, county of Middlesex and Stateof Massachusetts, have invented an Improved Book-Stitching Machine, for forming, inserting, and clinching staples, adapted especially for uniting together sheets of paper or other material, of whichthe following is a specifimechanism, by which `the` ends of the legs of the staple which project beneath the article are clinched after the staple has been insert!` ed; and a machine composed of these ele.`

ments constitutesthe iirst part of my inven- The other parts of my invention relate -toandconsist in certain combinations of the several parts of my machine.

vIn Figure l of the drawings, which is a side elevation of my' machine, the table to receive the article inwhich the staples are to be "inserted is marked A. `This table is provided with `a gage, B, in order that the staples may be `inserted with regularity, and this gage should be adjustable; This table` is attached to a stoutl slide, C, which is attachedby suitable Ways to the frame, "as shown in detail in Figs. 4 and 5, in order-that the distance ofthe table from the under surface ofthe overhanging arm may be varied as the thickness of the book or other article varies. This table is also pivoted by the pivots D-to the slide (Lin Order that the book may be, compressed, at certain points in the process,`between the upper surface of the table and the under surface of the overhanging arm.

`The awls aremounted on a stock, E, which reciprocates in the slide F, which is-attached to the overhanging arm by suitable Ways, as shown inV Figs. 1, 8, 9, 10, and 17, in order that the awls maybe moved sidewise, after puncturingthe book, to' allow the former and driverto come over the holes formed bythe The former Gr is also mounted on `a Stock, )EL-whichi reciprocates` in the slide F, in

' order that it may be brought over the lholes made by the awl, and be moved away to allow the aWl-stock E to Areturn to position for puncturing other holes.

within the former stock H, and, consequently,` moves .sidewise with theformer. The feedslide L is mounted in ways upon the overhangiug arm, and hasa motion toward and` h from the former-bed M, in order that when the Wire is fed forward by the feed-wheel N the orifice inthe feed-slide through which the wire is fed may abut uponjthe` groove in the former-bed into which the wire is to be fed,

and thereby make it certain that the end of wire, as it emerges t'romthe orifice in the feedslide, shall enter the groove in the l'Ormenbed.

`The .severing-knives P P are attachedto thev feed-slide-one rigidly, the otherby a pivotso that they'both move toward and from the former-bed with the feed slide. The formerbed M, by which, in connection with the former G, the staple` is formed from the straight y wire, is" in two parts, one of which, m, forms a portion of the under side of `the overhangi` ing arm,\vhile the other, mi, is'so mounted in a box, Q,- Which is part of the overhang ing arm, thatV it' may receive a slightl motion `toward and from the part m, in orderthat when in contact the groove across the top ofthe former-bed, which is partly in fmand partly in m1, may'` be complete, and that,

`Whenthepart m1 is moved away from the part y m, a free passage shall beleft for the staple and the driver J.

The clinchers R R are pivoted in a slot in the b ed A, and are vibrated around their pivots in such a manneras not only to bend `the projecting part of the legs of the staples, but alsol to cause their grooved faces `to press closely against the under side of the book af-` 'ter the staple has been inserted, and thereby' not only to'clinch the legs ofthe staples, but

also to embed the extreme ends of the staples in the book. The book is at the same time compressed between the table and the overhanging arm. y The" Operation is as follows: The wire is The driver J is mounted on a stock, K, which reciprolcates` by means of the slide C and the cam c.

a set-screw, by whichthev cani-shaftcl4 is prek 1 reaches the knives l) P. The table A is then set so that vits surface is at the proper distance from" the under' surface of thev overhanging varmthat is, far enough to allow the article tofbe operated upon to be moved freely betweenthe two surfaces,but not so far as to prevent '.,thelcompression of the articlelbetween the twosurfaces 4by the motion of the tableA upon the pivots`D'D. This is dene o is vented from turuing,-and the slide G thereby heldin place after it is-set. The motion of the table -A onj'the pivots D D is caused by the cams a a. The gage B is then set to the requireddistance from the slot in the tableY in .which the clinchers R R -are pivoted. The ed ge of the book is held close up to the gage B, `and power4 is applied, by means of thelej'V ver S, vclutch S1, and pulley S2, to revolve the' maidshaftfll. .The canis'wa cause .the table A to move slightly on thel pivots D D, and thus* compress'the pamphlet iir'mly between l theupper surfaceof the table and the under surface ,of the overhanging arm. A doubleactin g' cam, e, actuates thellever e', whichy actu-r atestheawl-stock E, and thus punctures the pamphlet. The points ofthe awls, afterpassing Ithrough 'the'pamphlet, en'ter'the slot in whichftheelinchers are pivoted. While the awls are thus moved the feed-ratchet lever n is'thrown forward, (by the cam ro'z1, actingV through `the lever n2. and vconnecting-rod 023,), carryingits ratchet with it, and immediately afterward the feed-slide L is thrown forwardbya cam-groove on the' same wheel asthe.

vuntil its end is close upto the foriner-bedfM, the'oriee'in the feedslide y and vthe end ofthe wire vlying in it being thus brought in line with the groove inthe'tormer-bed M; During these movements of-theratchet-lever u and the feed,-

l slide-'L the slide F is moved (by means of the l atsuc'h a` distance from the former-bed M that 't the wire when cut shall project equally on each side of the former-bed M.

'As soon as the feeding forward of the wire is accomplished the driver J is' caused to drop far `enough to clamp the wire uponr the formerl bedM and in its groove 4by means of a slight depression in the periphery of the cainj, which Hallows the lever jl to be moved by the spring j2," v vhi ch t hus,vthrough the vconnecting-rod3'3,

ing`b'rought directlyT in line`with thetholes through thebase of the bed M, through vwhich the awls 'pass to puncture the pamphlet, and also directly'in line with the holes formed 'by the awls. Thepart mi ofthe former-bed'M is then moved sligh'tlyaway from the part m',

(by the'camm2 acting through the lever `m3,)

and the driver J is thrown down by its spring j?, carrying the staple with it, and'forcing itis legsginto the holes made 'bythe awls.

R R are swung upward on their pivots,(by

the cam r acting through the lever r', whose fulcrum is at 1),) thus bending inward the projecting portions of the legs of thestaples,

and' forcing their extreme ends slightly into rlhe formi the driver is also lifted by its cam j and .lever jl, and the table A is lowered away from the overhanging arm, (by the spring lat and the shape of the canisa a,) relieving the pamphlet' from compression, so that it can be readily moved into position to receive a second staple,r l or so that it can be removed and a 'second pamphlet substituted. After the former G 'and driver J have been lifted, the slide Fv is moved sidewise (by its cam y,rock-shaftfl, i and connecting-rod f2) until the awls are" brought into position again. rlhe part m1 of the former-bed M is thrown into contact with the part m (by the spring m4 and the shape of the cam lm2) before theawls-descend, in order that the awls may be supported onl all sides l and close to the paper, as they puncture the paper.

In the feeding mechanism, n4is astiff spring, which sustains the Wheel N at its free end,

and by which the wire is forced up against f the wheel N, and into the feeding-groove of vthat wheel, v i Y The length of the staple lnay be varied by I means of .the slots in the levers n2 and l1.

It is obvious that the feeding andiforming mechanism above described may be used in combinationto manufacture staples.'

The driver J remains depressed until the clinchers- These staples might then be'fed, by proper yrnechanism im; e machine eed@ yup, Of the, Pamiers K168,736 Y i 3 ing, driving, and clinching mechanisms above described, and thus two separate machines be i -used todo Athe workdone by my machine.

It is also obvious that many changes may be made in the means for imparting motion `by the. acting parts without substantially `changing the machine. It is possible, also, to

compress the pamphlet on a stationary table; but I prefer to give the motion to the table for this purpose.

The end of the wire, as it leaves the feedfslide, enters directly into the groove in the former-bed. The wire is securely held in this groove by the driver until it is formed into a staple. After it is formed the staple is surrounded on all sides by solid metal untilitis driven, and its legs enter the holes in the 'ari ticle to be operated upon as soon as they leave the holes in the upper` clamping-plate--the lower part of the former-bed M.

These features are of great importance in my machine, in which the staple is both formed and inserted, as theymake it almost impossible for the wire to go Wrong.

It is also of very great importance that the article be properly clamped; and in my machine it is so clamped from the beginning to the end. 'lo accomplish this result I have4 formed oneofthe clamping-plates so thatboth the awls and the driver can act through it, both being guided by it to precisely the same point. I have also formed a slot in the other clamping-plate, through which the clinchers act, and into which the points of the awls enter after passing through the pamphlet.

Bv these means the pamphlet is firmly clamped before it is punctured, and kept so clamped until the staples are clinched.

What I claim as my invention is- E A1. rIhe combination of the-work-supporting table A with the vertically-adjustable slide C by means ofthe pivots D, as described.

2. The combination of the Work-supporting table A, pivoted at D and operated by cams i a, with the overhanging described.
